Specification of Letters Patent.

Patented May 9, 1922,

Application filed August 10, 1915. Serial No. 44,698.

To all whom it may concern:

Be it known that I, CHAnLns L. BRALEY, of Chicago, in the county of Cook, and State of Illinois, have invented certain new and. useful Improvements in Yoke-Ironing Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

My present invention has for its object to afford an improved and novel mechanism for ironing or pressing the yoke and shoulder portions of a shirt, shirt waist or the like and is in the nature of an improvement on the construction shown and described in my application Serial No. 878,058,'filed December 19, 1914, and embodying in general, a bed for supporting the yoke and shoulder portions of a garment, having a neck band expander arranged thereon, and pressing members cooperating with the bed on opposite sides of the neck band expander an arranged to be brought into close pressing relation with the expander irrespective of the size of the neck hand. More particularlythe object of the present improvement is to afford a practical and efficient mechanism for carrying out the purposes mentioned and whereby the several operations can be more readily effected. Another purpose of the invention is to provide an improved form and arrangement of parts for operating and also for heating the movable pressing members. Tothese and otherends the invention consists in certain improvements and combinations of parts all as will be more fully described hereinafter, the novel features being pointed out in the claims at the end of the specification.

Figure 12 is a detail sectional view on the line 12-12, Figures 7 and 8.

Similar reference characters throughout the several views indicate the same parts.

The present embodiment of the invention, which illustrates a preferred manner of carrying my improvements into practical operation includes a frame comprising a base 1 and an upright portion or standard 2 having a rear vertical extension 3. Mounted on the upper forward portion of the standard 2 is a hollow support 4: upon which is formed the bed 5 also preferably hollow, and which may be supplied with a heating medium through supply and discharge pipes 6, and passages 7. The upper surface of the bed 5 has a padded covering 8 while its under side affords a smooth ironing surface 9 that receives the inside of the shirt or garment, which is held against the-ironing surface 9 by means of a clamping member that will be described presently. The upper and lower surfaces of the bed meet along the line of its end edge, which serves, with the co-operating pressing members, to produce a fold in the pressed garment. The bed 5 is also provided on its upper surface with a neck band expander designated generally at 10 and embracing means for stretching the neck band of any size shirt after the well known manner in this class of machinery. Arranged for engagement with the upper or padded surface of the bed is a pa1r of separate pressing members cooperatlng with the bedv on opposite sides of the neck band expander and I will now describe the means f supporting and operating said pressing members.

11 is a carrier or frame that is swingingly mounted with relation to the bed in the bearings 12, and provided with suitable means in the form of handles 13 for lowering the carrier to bring the pressing members down onto the bed. The carrier 11 includes a pair of heating members or chambers 14, preferably cylindrical, upon which the pressing members are slidably arranged. To this end each pressing member, designated at 15, as shown in Figure 8, includes a cylindrical opening 16 for engagement with the heating chamber. The pressing member 15 also 1ncludes an upper portion 17 carrying antifriction rollers 18 which engage a guide 19 mounted on the carrier. 20 is a spring arranged within the hollow guide 19, and affording means for" actuating the pressing member inwardly, or toward the neck band expander during the downward movement of the carrier as appears in Figure 8. To this end the' spring 20 cooperates with a movable abutment 21 which is connected to the pressing member by a pin 22, and the tension of the spring 20 can be adjusted by means of the movable abutment 23 controlled by the threaded stem 24. The construction and arrangement of both of the pressing members is the same, and for convenience T have described only one of these. The heating members 14 may be supplied with a suitableheating fluid in any desired manner. For this purpose the crawings show said members provided with inlet and outlet openings 25, 26 communicating respectively with steam supply and discharge pipes 60, 61., respectively. Each arm 11, as shown in Fig. 12, is cored out to form a passage 62 communicating with the opening 25 or 26 and also communicating with the chamber within the cylindrical member 1 1. Said chamber. marked 63 in Figs. 8 and 12, also communicates by way of a passage 64- with a passage 65 lying above passage 62 and which at its end communicates with the passage through a pipe or conduit 66 extending transversely across the machine and connect ingthe two arms 11, as shown in Fig. 7. The flow of heating fluid is therefore from the supply pipe 60 through passage 62 in one arm to the chamber 63, around the bafiie wall. 67, thence through passages 64 and 65 to the conduit 66, and thence through the same passages and chambers in the other arm'll but in reverse order and finally to the discharge pipe 61. During the upward movement of the carrier the pressing members are moved away from the neck band expander in opposite directions by means of projections 27 on the main frame, carrying antifriction devices 28 which engage cams or curved arms 29 carried by the pressing members and operating to move the latter from the position shown in Figures 6 and 7 in opposite directions away from each other. The pressing members also include means for engaging the upper surface of the neck band expander, preferably in the form of a flange 30, which therebyserves to force the latter downwardlyinto tight engagement with the bed, while the inner edge 8.1 is brought into engagement with the side of the expander so as to iron the surface of the garment closeup to the neck band.

After the pressing members have been brought into engagement with the bed by lowering the frame, it is necessary to apply additional pressure to complete the ironing operation, and with this in view I arrange on the main frame a pressure device which may comprise a pivoted lever 32 provided with yieldable plungers 33, one arranged for cooperation with each of the pressing members after the latter are in pressing position, and acting to force the latter-tightly into engagement with the bed when the lever 32 is actuated in'the manner that will be described presently. The carrier is rovided with an extension 34L weighted at 35 for returning the carrier to its normal position shown in Figure 1, and 36 is a spring connected to the lever 32 for maintaining it in normal position.

The bed 5 has a yieldable table or surface 87 in advance thereof, for supporting the body of a garment. The garment is forced into engagement with the'ironing surface 9 by means of a padded clamping memher 38 which is mounted on a frame 39 by means of yieldable plungers 40 and 41 that permit the clamping member to be moved into proper engagement with the bed by a resilient, yielding action. The frame 39 is pivotally connected to link 42 mounted at 4-3 at one end and connected to a toggle joint comprising links 1 1 and 4:5. i

The link 15 is fixed on a rock shaft 46 carrying a link 47 to which is connected a rod 48 and 4:9 is a treadle lever pivoted at 50 and operatively connected to the rod 4-8. When the lever 1-9 is operated, the toggle joint is straightened and locked causing the clamping member to be brought into en gagement with the ironing surface ofthe bed, and to release the clamping member, treadle 51 is operated, engaging projection 52 on. the lever 19, and elevating the latter causing the toggle joint to be broken and thus releasing the clamping member. I also provide for applying pressure to the pressing members on the carrier simultaneously with the engagement of the clamping member onto the bed and with this in view, the lever 32 carries an extension 53 having cam surfaces 54: thereon arranged to be engaged by a roller 55 on a bell crank lever 56. Pivotally associated with the latter is a connecting rod 57 in turn pivoted at the center of the aforementioned toggle joint so that when the latter is operated to effect movement of the clamping member, the bell crank lever 56 is also actuated, elevating the rear end of lever 32 and lowering its front end in the manner shown in Figure 4 whereby sufiicient pressure is applied to the pressing members.

The operation of the machine, briefly is as follows: The parts are normally in the position shown in Figure 1 and in applying a garment such as a shirt for instance, it is positioned over the bed with the inside of the yoke underneath engaging the ironing surface 9 and the neck band secured about the neck band expander. The portions of the yoke at the sides of the neck band are then arranged upon the bed in such position that the seams in the garment between the yoke and bosom portions are transverse to the length of the bed. Thereupon the carrier is swung downwardly by hand to bring the pressing members into the proper relation with the bed and neck band expander as indicated in Figures 2, 6 and '7. In this position the pressing members hold the bosom and yoke portions at the sides of the neck band in the proper position, clamping it to the bed so that the operator can stretch the yoke underneath the bed into proper pressing position beneath the same. The parts are now in position to effect pressing and this is done by depressing the treadle lever 49, bringing the clamping member 38 upwardly and forwardly into engagement with the under surface of the bed and at the same time applying the required pressure to the pressing members on the upper surface of the bed. The bosom and yoke pressing members, when applied under pressure to the upper and lower surfaces of the bed, produce a fold in the garment along the end edge at the neck band end of the bed. This fold may be utilized as a base line with relation to which the remaining portions of the shirt are folded and pressed, so that the finished product is symmetrical with said fold line substantially tangent with the neck band and the shoulder seams square with the length of the shirt. The parts are released. by operating the treadle 51 as aforestated and the carrier is then swung upwardly and backwardly by the operator engaging the handles 13. a
